VEHICLE - BUILDING
INSTRUCTIONS
|
1
Cut and build the main frame
[chassis]
|
 |
Cut the five pieces of wood that form
the main frame, or chassis.
You can drill the 5mm diameter hole before or after gluing.
Glue the pieces together - flat on a table top or board.
Fit the 2 triangles. Put a dowel through the holes while gluing to keep
them level.
|
2
Assemble front axle
|
The
10cm long axle beam must be drilled [5mm] exactly in the centre. The dowel
front axle is glued under the beam, [It blocks one end of the hole]
Use two strips of sticky tape to keep the dowel in place while the glue
dries.
The short dowel pivot can be fitted in the hole.
If it isn't a good tight fit then glue it in place. |
3
Build and fit wheels
|
  |
The card discs are
too thin for suitable wheels - the system shown opposite solves the problem
by using a card square to increase the thickness at the centre, where it
matters most. Two small pieces of wood are use as spacers. The best way
to line up the holes in the disc and the square is to make yourself a JIG,
as shown. It is just a piece of dowel fitted into a block. Build all the
wheels on the dowel of the jig. |
  |
There are other ways to build wheels using card
discs, but for them you
will need 2 discs for each wheel. See opposite.
Assemble your vehicle using paper or plastic spacers
to position the wheels on the axles and using plasic tube 'stoppers' to
keep the wheels from falling off.
DO NOT glue the pivot into the hole in the chassis
or it will not steer!
